Dear all,
I'm involved modeling a fully jacketed line (Except for flanges and valves) with some cross fitting wherever directions chanches are needed.
Finally I decided to model a cross as a four pipes comming to a single point and enterig the SIF values of a welding T for the intersection node in all four elements. I'm not sure if this is a good way of modeling such a component, but due to my time limit, that's best I can do.

I need to mention that because the line is jacketed, I used anchor-CNode at every cross ( Intersection node) to make core and jacket dependent.

Now I'm having a strange output!

I get a sustain overstress report in one of the intersections (crosses) which should'n exist due to my support arrangement.
As I remove the Cnode-Anchor on that node, the sustain stress reduces by 50% and instead, I get expansion overstress which didn't exist before! This is really strange to me as I'm sure system doesn't need any extra rest support for its weight.

Please advise me
Best

Hi micvanzil
Yes result is strange.
can you attached the caesar file here or send to habibur21@gmail.com

Dear shr,
Unfortunately we don't have any access to the internet on our computers in the company. That would be best if somone could take a look at the model but there is not such a possibility.
